| Aerobic | Oxygen containing |
| Anaerobic | Oxygen Lacking |
| Cellular Respiration | Aerobic harvesting of energy from food molecules by cells |
| Redox Reaction | movement of electrons from one molecule to another |
| Oxidation | loss of electrons from one substance |
| Reduction | addition of electrons to another substance |
| Dehydrogenase | Enzyme |
| NAD+ | organic molecule that cells make from a vitamin, use to shuttle electrons. |
| Chemiosmosis | cells use potential energy in concentration gradients to make ATP. |
| ATP Synthases | protein clusters that reside in the membranes. |
| Substrate level phosphorylation | an enzyme transfers a phosphate group from an organic substance molecule to ADP. |
| Glycolysis | begins respiration by breaking glucose into two molecules. |
| Krebs cycle | completes breakdown of glucose |
| Intermediates | products formed |
| Acetyl CoA | high energy fuel molecule for the Krebs cycle |
| Alcoholic Fermentation | productoin of ethanol from glucose |
| Lactic Acid Fermentation | lactic acid is produced when NADH from glycolysis is oxidized |
| Strict Anaerobes | requiring anaerobic conditions and are poisoned by oxygen |
| Facultative anaerobe | can make ATP by either fermentation of Chemiosmosis |
